In recent years, more than 100 trolley-buses and a number of tramcars have been produced in a serial way.

Meanwhile, a newly-developed subway train has been run in the Pulgunbyol-Puhung station section.

All those achievements are attributable to the patriotic devotion and efforts of Supreme Leader Kim Jong Un for the citizens.

Visiting the Kim Jong Thae Electric Locomotive Complex in July Juche 104 (2015), the Supreme Leader gave a task to manufacture a Korean-style subway train in the shortest period. And he examined its miniature and solved all the problems arising in its development and production.

When a new subway train was produced, he pointed out its shortcomings one by one and learned in detail about its trial operation by train.

Meanwhile, he indicated orientation and ways for modernizing the Pyongyang Trolley Bus Factory on several occasions and settled knotty problems arising in its modernization project.

He visited the factory in late January 2018 and gave an instruction for making trolley-buses with the people's demand and estimation as an absolute standard.

A few days later, he got on the newly-made trolley-bus in the late evening to confirm in detail its safety for a long time.
